Musical periods before the 1960s did not capture the essense of modern stereo recording,
which began to take shape in the 1960s and 1970s. Yet, many early jazz recordings still stand up
because of the great performances. Jazz engulfed a wide variety of music that included
Dixieland, marching bands, gospel, blues and experimental music. By the sixties there were several
subgenres of jazz that included jazz fusion, progressive jazz and jazz/funk. Artists who helped
advance jazz beyond common formulas included Miles Davis, Herbie Hancock and Dave Brubeck. Many
pop hits of the seventies by artists such as Chicago, Tower of Power and Average White Band were
heavily influenced by jazz horn sections.
